Navigation commands

There are several commands that are useful in moving from one part of the menu tree to another. The commands are similar to those used in a UNIX® shell:

cd

This command moves you to a given spot in the menu tree. Entering

 

cd / always takes you back to the main menu.

pwd

This command displays the current menu path where you are in the

 

menu tree.

up

This takes you back to the last menu that you touched.

.. or cd ..

Both of these commands take you up one level in the menu tree.

pushd and popd

These commands allow you to manage a stack of menus that you visit

 

frequently.

history

This command displays the last several commands that you entered.

 

You can reuse these commands by typing an exclamation point (!)

 

followed by the number of the command as displayed.

quit or exit

Both of these commands terminates your session.

Configuration control commands

These commands control the effectiveness of changes to the switch configuration. The general rubric for configuring the switch is EASY:

￿E for editing the configuration, typing in your changes

￿A for the apply command which makes the changes part of the running configuration

￿S for the save command which writes the changed configuration to flash memory

￿Y for yes, which is the answer to the prompt to be sure that you really want to update flash

Additional configuration control commands include the following:

diff

This command displays the differences between the most recent edits

 

and the running configuration.

diff flash

This command displays the differences between the running

 

configuration and its flash copy.

revert

This command discards all changes which have not yet been applied.

revert apply

This command discards applied changes which have not yet been

 

saved to flash.

Additional commands

These are additional commands that facilitate troubleshooting or are otherwise helpful:

ping

Sends ping, Internet Control Message Protocol (ICMP) echo, requests

 

to the specified IP address.

traceroute

Traces the IP path to a specified IP address.

who

This command shows who is logged on to the switch and from which

 

address.

telnet

Opens a Telnet session to the designated IP address.

verbose

Tailors the level of messages displayed on your session.

lines

Controls the number of lines per screen for display purposes.
